Common Bus Fusing Requirements
When using a Kinetix 6000 leader IAM module, DC-bus fuses are required
only when wiring to more than one Kinetix 6000 follower IAM module.
When wiring multiple follower IAM modules, terminal blocks are required to
extend the DC common-bus power to additional drives. Install fuses in both
lines of the DC bus between the DC bus terminal block and each follower
IAM module. Base these fuse ratings on the DC input current of each follower
IAM module.
When using a non-Kinetix 6000 common-bus leader drive, DC bus fuses are
required in both lines of the DC bus, between the common-bus leader drive
and follower IAM module. Base these fuse ratings on the common-bus leader
drive DC output current. When using more than one follower IAM module,
install fuses in both lines of the DC bus between the non-Kinetix 6000
common-bus leader and the terminal block as well as between the DC bus
terminal block and each follower IAM module.
Refer to Circuit Breaker/Fuse Options on page 28
, for recommended circuit
breaker/fuse sizes. Refer to DC Common Bus Wiring Examples on page 193
for interconnect diagrams.
Set the Ground Jumper in
Select Power Configurations
Setting the ground jumper is required when using an ungrounded, corner-
grounded, and impedance-grounded power configurations. Setting the ground
jumper is also required when the Bulletin 8720MC regenerative power supply
or any active converter provides DC-bus power.
Setting the jumper involves removing the IAM module from the power rail,
opening the IAM module, and moving the jumper.
Setting the ground jumper is best done when the IAM module is removed from
the power rail and placed face-up on a solid surface equipped as a grounded
static-safe workstation.
IMPORTANT If you have grounded power distribution, you do not need to set the ground
jumper. Go to Grounding the Kinetix 6000 Drive System on page 95
.
ATTENTION: Because the unit no longer maintains line-to-neutral voltage
protection, risk of equipment damage exists when you move the ground
jumper.
ATTENTION: This drive contains electrostatic discharge (ESD) sensitive parts
and assemblies. You are required to follow static-control precautions when
you install, test, service, or repair this assembly. If you do not follow ESD
control procedures, components can be damaged. If you are not familiar with
static control procedures, refer to Guarding Against Electrostatic Damage,
publication 8000-4.5.2
, or any other applicable ESD awareness handbook.
